SEED-DRILL HOE.

.SPECIFICATION formingpart of Letters Patent N 0. 672,916, dated April30, 1901.

Application tiled January 5, 1901. Serial No. 42,153. (No modela "0 allwhom t may concern.

Be it knownthat we, JOHN S. ROWELL and SAMUEL W. ROWELL, citizens of theUnited States, and residents of B eaverdam, in the county of Dodge andState of Wisconsin,

have invented certain new and useful AImprovements in Seed-Drill Hoes;and we do hereby declare that the following is a f ull, clear, and exactdescription thereof.

Our invention has for its object to stiifen the Shanks and shoes ofdrill-seeder hoes, as well as to insure of their being kept in linewithout interference with their ready automatic yield when meetingobstructions of i5 more than ordinary resistance, said inventionconsistingin certain peculiarities of construction and combination ofparts hereinafter particularly set forth with reference to theaccompanying drawings and subsequently claimed. Figure l of the drawingsrepresents a side elevation of one of our improved drill-seeder hoes,partly broken and in section; Fig. 2, a plan view of the saine invertedand partly in horizontal section, as indicated by lines 2 2 in the firstfigure; Fig. 3, a partly-horizontal section plan View of a portion ofthe hoe, this view being indicated by lines 3 3 in said first figure;Fig. 4, a perspective View of a spring clip that constitutes part of thehoe, and Fig.

3o 5 a like view of a hanger engageable with the clip.

Referring by letter to the drawings, A indicates the hollow shank, and Bthe shoe, of our improved seed-drill hoe, these parts being of ordinaryconstruction, except that said shank is provided with an upper forwardear Z9, to which the rear ends of a pair of forwardly-diverging metalbrace-bars O are bolted or otherwise rigidly secured, the other 4o endsof these bars being provided with apertures engaged by trunnions c of ahanger D, that is made to fit a seed-drill cross-beam and be fastenedthereto, such'a beam being illustrated by dotted lines in Fig. l. Boltedor otherwise rigidly connected to the forward end of the shoe B andinloose fit on trunnions c of hanger D is another pair of diverging metalbrace-bars E, the forward ends of these bars being lapped by thecorresponding ends of 5o the bars O aforesaid.

A brace F of hanger D is made to constitute a pivot engaging theguttered head of a clip F, said brace being in line with the trunnionsaforesaid, and bolted or otherwise rigidly secured to the tail of theclip betweenV varying the working throw of said link-bar.l

The clip H is made wide enough to come up against the under edges of thebars C when the spring G is relaxed, so that the hoe may be readilylifted clear of the ground by sufficient tilt of the aforesaid crank.

Bolted to the bracebars O'is an intermediate metal block J, arrangedunder the forward portion of spring-bar G, and a set-screw h is providedin the block central of same to serve as an adjustable fulcrum forvarying the tension of said spring-bar when the hoe is in workingposition. y

The hoe-shank is provided with rear ears rljfor the connection therewithof the supporting-frame and tension-spring pertaining to a press-wheel,and another rear ear la on said shank is for the attachment thereto of achaincoverer, these ears being common in the art to which our inventionrelates.

g From the foregoing it will be readily appreciated that we provide asimple, very strong, and stiff seed-drill hoe that cannot swing side-Wise and get out ofline when at work. Hence we avoid chang f theliexible tube, that in practice engages the hoe-shank, vand we also doaway with the unsatisfactory spring-fork brace that is commonly arrangedto have sliding movement longitudinally of said hoeshank, theseadvantages being due to the brace and spring-bars arranged and connectedas herein shown and described, all of said bars being pivotal on thesame axis.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is-

l. The combination of the hoe-shank and shoe, forwardly-divergingbrace-bars having rear-end union with said shank, other forwardlydiverging brace bars in rear end union with said Shoe, an intermediatespringbar, means pivotally connecting the forward ends of all the barson the same axis, and a spring-bar fulcrum in connection with a setofthe brace-bars.

2. The combination of the hoe-shank and shoe, forwardly-divergingrbrace-bars having rear-end union with said shank, other forwardlydiverging brace bals in rear end union with said shoe, an intermediatespringbar, means pivotally connecting the forward ends of all the barson the same axis, and an adjustable spring-bar fulcrurn in connectionwith a set of the brace-bars.

3. The combination of the hoe-shank and shoe, forwardlydivergingbrace-bars having rear-end union with said shank, otherforwardly-diverging brace-bars having rear-end union with said shoe, anintermediate springbar, means pivotally connecting the forward ends ofall the bars on the saine axis, a fnlcrum for the spring-bar inconnection with a set of brace-bars, and a clip fast on the rear end ofsaid spring-bar, the clip being wide enough to come against the underedges of the uppermost brace-bars when there is sufficient lift of theaforesaid spring-bar.

4. The combination of the hoe-shank and shoe, forwardly-divergingbrace-bars having rear-end union with said shank, forwardlydivergingbrace-bars having rear-end union with said shoe, an intermediatespring-har, a hanger with which the forward ends of all the bars are inpivotal connection 011 the same axis, and a spring-bar fnlcrnrn inconnection with a set of the brace-bars.

5. The combination of the hoe-shank and shoe, brace-barshaving rear-endunion with said shank, other brace-bars having rear-end union with saidshoe, a clip having a guttered head, a spring-bar fast at its forwardend to the tail of the clip, a hanger with which the brace-bars and clipare in pivotal connection, a fulcrum for the spring-bar, and anotherclip fast on the rear end of said spring-bar, the latter clip being wideenough to come against the under edges of the uppermost brace-bars whenthere is sufficient lift of the aforesaid spring-bar.

6. The combination of the hoe-shank and Shoe, brace-bars having rear-endunion with said shank, other brace-bars having rear-end union with saidshoe, a spring-bar, means pivotally connecting the forward ends of allthe'bars, and a block made fast between the uppermost brace-bars unilorthe forward Dortion of the spring-bar.

7. The combination of the hoe-shank and shoe, brace-bars having rear-endunion with said shank, other brace-bars having l'ear-end union with saidshoe, a lspring-bar, means pivotally con necting the forward ends of allthe hars, a block made fast between the nppermost brace-bars under theforward portion of the spring-bar, and a setscrew in conjunction withthe block in opposition to said spring-bar.

ln testimony that we claim the foregoing we have hereunto set our hands,at Beaverdam, in the county of Dodge and State of Wisconsin, in thepresence of two witnesses.
